When in doubt, eat a banana. That’s been the unspoken rule of club runners, park joggers, and middle of the pack marathoners for decades. And for good reason.
Bananas are one of the most run friendly snacks out there. They’re packed with carbohydrates, easy to digest, and come with their own natural wrapper, no fiddly foil, no sticky gels, no exploding packets down your shorts mid race. Just peel and go.
What makes them great for runners is the combo of natural sugars (glucose, fructose, and sucrose) along with a decent whack of potassium. That potassium helps with muscle function and may help reduce cramping, though let’s be honest, if you’re cramping at mile 24, a banana three hours earlier probably isn’t going to save you. Still, it might’ve helped.
They’re also kind to the stomach, which is a blessing when you’re trying to avoid a Code Brown situation during your tempo run.
When to Eat One
If you’ve got 30 to 60 minutes before your run, a banana is ideal. It won’t sit in your stomach like a regretful breakfast burrito, and it gives you just enough fuel to keep things ticking over. It also doubles as a quick post run snack if you’re not ready for a full meal straight away.
Not Just for Elites
Watch any elite marathon coverage and you’ll see tables lined with tiny bottles, custom labelled drinks, and scientific precision. Then look at your own kit bag and find a slightly bruised banana from last Tuesday. That’s okay. We’re not breaking world records her, we’re just trying to get through the session without collapsing or crying.
Final Word
Is a banana the perfect fuel? No. But it’s cheap, it works, and it won’t leave your fingers stuck together like a half squeezed gel packet. Long live the bendy fruit.
